This paper summarizes a systematic study of the Cascade Finishing Process and its ability to improve surface finish. Although mainly used to deburr castings and machined parts, the process was able to improve surface finishes under the right conditions. Using abrasive media, the vibratory action produced directional, matte surfaces with R(sub a) values as fine as .27 micrometers. Surfaces perpendicular to the vibratory motion were found to have undergone a peening action with surfaces having initial R(sub a) values reduced by up to 75%. Run time, vibratory frequency, media type, surface roughness and surface orientation are all major factors governing the process.
